Saving folder "view state"

When using Search Folders, it’d be nice if it saved the view state when going away/back to a particular folder. For instance if I’m grouped by tags as shown here:

…but I then click off to an Inbox or some other folder and then come back all groups default to expanded view and I have to manually collapse them all (except for 2 in this example). I get that that might be too onerous to do for -ALL- folders (ie saving the view) such that we -want- those to redraw with the default view options in case you’ve mucked with the settings for something specific. But maybe an option to tick on just for Search Folders? Or maybe globally but only if someone opts in?
